create_line · LLV Helix Framework MCP: Risk & Policy

WHAT IT DOES

What create_line does on LLV Helix Framework

AI agents use create_line to create or update resources in LLV Helix Framework — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LLV Helix Framework environment.

WHY IT NEEDS A POLICY

Why create_line needs a policy

The tool creates or adds new data (a line/connection) within the framework's creative workflow system, which is reversible and has no side effects beyond adding information to the system state. This aligns with the Write category: creates or modifies data reversibly.

From the tool's definition Tool name 'create_line' and description 'Create a line - a connection or path between points' indicate it creates or establishes new data structures (lines/connections).

What risk level is create_line? +

create_line is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_line? +

Yes. Add a rate_limit block to the create_line rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
